Deadbolt FlexPin

Great plug, so easy to insert wire and locks down great.

Recently purchased a 5.1.2. speaker set up. With exception of the sub, all the speakers were push down spring loaded connections. Suuuuure I could have gone bare wire, but what fun is that? The installation is as simple as presented in the listing. The flex pins are high quality. Was having an issue with a particular speaker and ended up hooking up, unhooking, rehooking it up multiple times. The flex pin held it's shape perfectly. No deformation or fraying. Really glad I got these. One thing to consider when using is proximity of one pin to another. I don't know how much of the plug is conductive. Are the exposed metal collars are conductive? Will they short of they touch? Don't know. Don't want to find out. To be extra cautious, I wrapped the collars of the negative pins in electric tape. Some day, will go back and use black shrink tubing if the spirit moves me. Only did the negative side, because didn't have red tape, and the area of the speaker the pins go in have nothing conductive near by. So protecting just one collar essentially protects both. If not wanting to raw dog bare wire into your speakers and don't have 5-way connectors on your speakers to use banana plugs, this is the way to go. Hope this review helps with your cable termination purchasing choice. Take care. :)

Works great for vintage receivers with spring loaded speaker connectors.

Be aware that they are wider than most plugs so if space is tight you might not want these. However if that's not a problem then I find them the best most versatile plugs that I've tried. They are missing the boat though. They really need to make it so you can also use it like a regular banana plug too. That would make them the swiss army knife of connectors. You can hack them with spring steel wire but it's a pain and I'm not sure how good the conduction is. Still waiting for the perfect plug.

I have a mix of new and more vintage audio equipment. A few years ago I purchased some Bluejeans Cable for my speakers and amplifier. The cable made by Belkin is a thicker 10 AWG size, sometimes called "10 White". I was using a smaller thinner cable the last couple of years because while the Bluejeans cable fit into a newer Prima Luna amp, the connectors on my circa 1980 Macintosh, MAC 4100 has spring clips. The wire barely fit into the spring clips and if I moved the receiver or the speakers, the cable would come out and I'd have to reconnect. I got tired of doing this and just stopped using the cable in favor of a different thinner type. That was fine, but most people listening to audio/hi-fi always like to try new equipment, even if that stuff is 30 years old. I purchased some DCM TF-600 speakers a few weeks ago and wanted to hook them up to the Mac with the Bluejeans cable. The cable barely fit into the Mac, although I did get it to hold, but with the speakers when I moved them into a different listening position, the cable would come out. Those speaker are about 30 years old and the cable was too large to wrap about the post, and the hole to put the speaker through was really too small for that 10 AWG size cable. I ordered these flex pin banana plugs which the manufacturer claimed would hold up to 10 AWG wire. The manufacturer was correct. Their directions are pretty clear, and you just need to strip some of the shielding off the wire, and unscrew the two piece banana plug. Push the wire through the bottom part of the plug and push the wire through. Fold down some the wire and screw the top part back on. The plugs were very easy to install through the banana plug speaker post holes and I was able to wrap part of the pin portion around the post. Since this pin is flexible, it was easy to do, although on one speaker I just pushed the pin through the hole and tightened it. Either way works equally well. I had a little more trouble getting the pins to stay in the Macintosh receiver speaker connections. I took my wire strippers and flattened the end of the pin and was able to push it in. This receiver is from around 1980, and while I did have it serviced a few years ago, the one spring pin speaker connector may not have been going down all the way. The Mac is heavy and it would have been a last resort to disconnect all the wires to it and remove it from the audio rack so I flattened the push pin slightly and it was fine. If I ever have the Mac serviced again I can have these old spring clips replaced, but what I did worked and the cables are secure in both the receiver and the speakers. I doubt I would have had any problem with smaller gauge wire but if you have vintage audio equipment with spring clip connectors and heavy guage cable these Deadbolt Flex Pin Banana Plugs will do the trick and make you life easier. I can highly recommend them.

Sometimes you have to hunt around for a flex pin top half that will fit into your spring terminal. I had an older Yamaha AVR that I went through three pins for the center channel connection before finding one that would work and insert properly into the terminal. It may have also been my AVR, I suppose - once I got it to insert, it inserted easily the second and subsequent times. Maybe some sort of oxidation on the terminal itself. Whatever. Great product. Cleaned up my connections, no more worries about stray wires from thicker gauges poking out and shorting, just looks cleaner and tidier. Very happy.

I am redoing my home theater and am happy with these plugs. They are easy to use and make for a very clean install. The quality is good and very happy with them!

Good product at fair price, shipped with care
